Scientific Background
Target data The protein expressed by the gene ESR1 functions as a nuclear hormone receptor involved in regulating eukaryotic gene expression, affecting cellular proliferation and differentiation in target tissues. It mediates ligand-dependent nuclear transactivation either through direct homodimer binding to estrogen response elements (ERE) or by associating with other transcription factors like AP-1/c-Jun, c-Fos, ATF-2, Sp1, and Sp3, allowing ERE-independent signaling. Ligand binding triggers a conformational change, facilitating the interaction with coactivator complexes through LXXLL motifs. This interaction leads to mutual transrepression with NF-kappa-B in a cell-type-specific manner, reducing NF-kappa-B DNA-binding activity and transcription from the IL6 promoter while displacing coregulators like RELA/p65. It can antagonistically or synergistically interact with NF-kappa-B for transcription activation, involving recruitment to adjacent response elements, working with CREBBP. Additionally, it activates the transcription of TFF1 and mediates membrane-initiated signaling through kinase cascades. It's crucial for MTA1-mediated transcriptional regulation of BRCA1 and BCAS3. Isoform 3 specifically activates NOS3 and endothelial nitric oxide production, while isoforms lacking certain functional domains modulate transcriptional activity by competitive ligand or DNA binding and heterodimerization with the full-length receptor, capable of binding to ERE and inhibiting isoform 1.
